Grid edit template Focus() throwing Exception

[Luke]

 I am trying to set focus to a textbox within the edit template and when it runs I get the following error:

A first chance exception of type 'System.NullReferenceException' occurred in NgeDataEntry.dll


 {"Object reference not set to an instance of an object."}

 

Not sure what I have wrong here. Can anyone spot the mistake.

 

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)

       {

           if (e.Item is GridEditFormItem && e.Item.IsInEditMode)

           {

               UserControl myUserControl = e.Item.FindControl(GridEditFormItem.EditFormUserControlID) as UserControl;

               string script = String.Format("$get('{0}').focus(); $get('{0}').select();", myUserControl.FindControl("RadTextBox2").ClientID);

               ScriptManager.RegisterStartupScript(Page, typeof(Page), "myscript", script, true);

           }

       }

Hello,

 if your code is not worked than also try with the below code snippet. 

GridEditableItem editedItem = e.Item as GridEditableItem;
            UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);

 

Also try to access same control into ItemDataBound event.

Let me know if any concern.

Thanks,

Hello Guys,

I want to share that you can also achieve this requirement directly on the client instead of calling the RegisterStartupScript method:

<ClientSettings>
    <ClientEvents OnRowCreated="rowCreated" />
</ClientSettings>

JavaScript:

function rowCreated(sender, args) {
    var item = args.get_item()
    if (item.get_isInEditMode()) {
        var textBox = $telerik.findControl(item.get_editFormItem(), "RadTextBox2");
        textBox.focus();
    }
}

Hope this helps. Please give it a try and let me know about the result.

Hi Luke,

I've already replied in the mentioned support ticket thread.
If you have difficulties implementing the suggested approach, I can prepare a sample runnable web site for your convenience and send it to you.
